Less repetitive work
Automate recurring supplier updates and reduce the mistakes that come with editing and importing files by hand.

Supplier Feed Automation & Inventory Sync
Messy feeds. Useful product data.
Automate supplier product data, inventory, and price updates across ecommerce platforms, POS systems, ERP/PIM software, marketplaces, and databases.
I build custom workflows around supplier APIs, CSV, XML, JSON, spreadsheets, and SFTP feeds.
Send me a supplier sample or API documentation and a description of the system it needs to update.
BUSINESS AUTOMATION, FROM SOURCE TO SYSTEM
Keep supplier data moving without manual work
Supplier inventory synchronization should fit your operations. Replace repeated downloads, spreadsheet edits, and imports with a process that applies the same agreed rules each time.
More current business data
Keep inventory, availability, prices, and catalog information aligned on an agreed schedule, reducing stale stock and pricing data.
Room for more suppliers
Add sources to a documented workflow and catch invalid data before it reaches your systems, without recreating every import.
WHEN STANDARD TOOLS DON’T FIT
When a custom supplier integration makes sense
A generic feed-import tool can work well for a simple connection. Custom automation becomes useful when standard applications cannot represent your matching rules, business decisions, or systems cleanly.
- Product identifiers don’t line up
Match supplier and destination SKUs using EAN/barcodes, MPN/vendor codes, or custom identifiers.
- Several suppliers overlap
Apply supplier priority or fallback logic, or combine inventory without counting the same stock twice.
- Stock needs business rules
Apply safety-stock buffers, caps, minimum/maximum quantities, and availability rules.
- Prices need calculations
Use agreed margins, rounding, currency conversion, or other price transformations.
- Catalog fields differ
Transform variants, attributes, and categories, including cases where different suppliers provide different fields.
- Sources need a custom connection
Handle unusual CSV/XML/JSON structures, SFTP deliveries, or a supplier’s own API.
- One feed serves several systems
Keep multiple downstream systems updated from the same agreed supplier-data workflow.
- Orders need a return path
Export orders to suppliers and bring fulfillment, tracking, and status information back.
- Bad data needs a review path
Validate incomplete or unexpected records before applying changes to business systems.
WORK WITH THE TOOLS YOU ALREADY HAVE
Connect supplier data to the systems you already use
From Lightspeed supplier inventory sync to ERP supplier integration, the destination shapes the workflow. Each connection starts with a review of the available APIs and data.
- Lightspeed
- WooCommerce
- Magento / Adobe Commerce
- BigCommerce
- PrestaShop
- ERP systems
- PIM systems
- Marketplaces
- Databases
- Custom applications
These are example destinations; other systems can be connected when suitable API or data access exists. I review the available endpoints, formats, and permissions before confirming feasibility. If your destination is Shopify, see Shopify inventory sync and supplier integration.
SOURCES, FIELDS, AND DIRECTIONSBuild around the data
Build around the data
your suppliers provide.
Supplier API integration and inventory feed integration begin with a representative sample. We agree what each source owns, which fields may change, and where updates should go. For connections between applications beyond supplier feeds, see Python API integration and data synchronization.
Supported supplier sources
- REST APIs and GraphQL APIs where available
- CSV, XML, and JSON
- Excel / spreadsheets and Google Sheets where appropriate
- FTP / SFTP deliveries
- Databases and downloadable supplier feeds
- Structured data from custom supplier systems
CSV inventory sync or XML product feed integration can be part of the same repeatable workflow as API-based updates.
What can synchronize
- Inventory / stock and product availability
- Cost and selling prices
- Product/catalog information
- Variants, attributes, and categories
- Product identifiers and multiple supplier feeds
- Orders, supplier fulfillment, and tracking information
The exact fields and direction depend on the project. Product data automation can update one system or distribute agreed changes to several destinations.
ILLUSTRATIVE WORKFLOWSDifferent systems.
Different systems.
One useful data flow.
These examples show how automated supplier feeds can support inventory, catalog, and order operations. The fields, direction, and scope are agreed for each project.

Business systemsAgreed destination
Designed around your workflow01 → 02 → 03
Supplier inventory → POS
- Supplier CSV / XML / API
- SKU / barcode matching
- Stock rules
- Lightspeed or another POS
POS inventory sync that turns supplier availability into agreed stock updates.
Multiple suppliers → ecommerce
- Supplier A API + Supplier B CSV + Supplier C XML
- Normalize and match products
- Supplier priority / combined stock rules
- WooCommerce / BigCommerce / Magento
Multi-supplier inventory sync, including WooCommerce inventory sync, built around how you source products.
Supplier catalog → ERP/PIM
- Supplier product feed
- Validate and map fields
- Transform attributes / categories
- ERP / PIM / database
Product catalog synchronization that prepares supplier data for your internal systems.
Orders and fulfillment
- Ecommerce / business system
- Export order to supplier
- Supplier fulfillment response
- Tracking / status update back to destination
An agreed order and fulfillment flow, when both systems provide suitable access.
VALIDATE BEFORE UPDATING
Built to fail safely
Reliable inventory automation needs a plan for missing files, changed formats, and uncertain matches. Reliability measures are selected according to your workflow and the risk of an incorrect update.
Check incoming data
- Input validation and missing-field detection
- Duplicate and ambiguous-match reporting
- Unexpected schema-change detection
Handle interruptions
- Safe retries and error logging
- Alerts / failure reporting where required
- Idempotent processing where relevant, so retrying does not repeat an action
Make issues traceable
- Clear records of skipped or failed items
- Testable mapping and transformation rules
- Agreed handling for incomplete feeds, rather than assuming missing records mean zero stock
WHAT YOU RECEIVEA workflow you can
A workflow you can
keep working with.
Maintainable Python source code, explicit field mappings, and documentation of important business rules. The handover covers setup/deployment instructions, the agreed automation schedule, configuration where appropriate, and required logging/error handling.
15 years of software development experience. I work with APIs, databases, and scheduled jobs, using Django, FastAPI, Flask, or webhooks where relevant to the project.
We agree on testing, deployment, and ongoing operation before development. Hosting and later maintenance are scoped separately when needed.
BEFORE WE START
A few useful answers.
How is this different from the Shopify service?
This is a general supplier-data automation service for ecommerce, POS, ERP/PIM, marketplaces, databases, and custom applications. The dedicated Shopify service focuses on Shopify products, variants, inventory operations, and locations.
Can you automate an existing manual import?
Yes. Send the original supplier file, the version you currently prepare, and a description of the steps. I review the source and destination access before confirming what can be automated.
Can several suppliers update the same catalog?
Yes. We agree on matching identifiers, supplier priority, combined stock calculations, and ownership of each field. Missing, duplicate, or conflicting records need explicit rules before updates are applied.
Can you export orders and return fulfillment or tracking data?
Yes, when suitable APIs or file access exist. We agree the fields, direction, order identifiers, and status rules, including how retries avoid duplicate actions.
How often can synchronization run?
The workflow can use an agreed schedule or available events/webhooks. Timing depends on supplier feed availability, destination API limits, data volume, and your operational needs.
What happens when a supplier changes its format?
Validation can flag missing fields or unexpected structure, with skipped-item records and reporting as required. A changed supplier schema may need a mapping or code update; that handling is agreed in scope.
Will I receive the source code and instructions?
Yes. The agreed deliverables include maintainable Python source code, field mappings, setup instructions, and important business rules. Deployment, hosting, and ongoing maintenance are discussed through Fiverr before you order.
